February FDA clearances slacken in number and significance
April 2nd 2006Vendors are off to a slow start this year in terms of FDA clearances, managing just 17 in February for a total of 38 for 2006. Only once in the last six years has the industry done worse: In 2004, FDA reviewers cleared just 35 devices in the first two months of the year.
Imagers explore PET/CT for lung cancer diagnosis
April 2nd 2006Challenges remain for PET/CT in diagnosing lung cancer. Key among them is bolstering detection without increasing false positives. But in several studies presented at the 2005 RSNA meeting, researchers explored the quantitative data derived by the hybrid technique, and their findings could move PET/CT closer to practical use for this application.
Feds appraise the value of nuclear medicine research
April 2nd 2006The government plans to spend nearly $800,000 to determine the strategic importance of nuclear medicine research, according to National Institutes of Health chief Dr. Elias Zerhouni. Society of Nuclear Medicine president Dr. Peter Conti is encouraged about the initiative.
Splash created by 64-slice CT obscures other radiology advances
April 2nd 2006No development since I began covering medical imaging in late 1997 has generated the level of excitement and potential for change as the 64-slice CT scanner. Plenty has happened in those years: the flourishing of CAD and virtual colonoscopy, 3T MR and parallel processing, continued advancements in ultrasound, PET/CT and SPECT/CT fusion imaging, and the ascendancy of PACS and imaging informatics.
64-slice CT enters clinical practice realm
April 2nd 2006After installing a 64-slice CT system at Metroplex Hospital in Killeen, TX, radiologists invited asymptomatic referring physicians to undergo a free heart scan and experience the new technology firsthand. After a coronary CT angiogram, three of the doctors left with an appreciation for the new scanner- along with a diagnosis of heart disease.
Dose concerns sway use of MR, CT in colon, brain
April 2nd 2006Among European radiologists, concerns about ionizing radiation exposure give MR an edge in specific applications, including colorectal cancer screening in younger patient populations. But in the U.S., such concerns have not dampened enthusiasm for CT, particularly in neurovascular studies.
‘Filet view’ software streamlines CT colonography
March 22nd 2006Imaging reconstruction software that “unfolds” the colon wall flat could greatly shorten reading time for CT colonography. Researchers from Argentina have found no significant differences in diagnostic accuracy between the “filet view” and conventional CTC in the first study comparing both virtual colonoscopy techniques.
Cardiac software promises boost in cardiac CT productivity
March 20th 2006New software from GE Healthcare can cut the average time needed to read a coronary CT angiogram to less than five minutes. Early use at Tennessee Heart and Vascular of the CardIQ Xpress, unveiled March 13 at the American College of Cardiology conference, resulted in physician reviews of 10 to 12 cardiac CTAs per hour.
CT, MR edge ultrasound in PVD utility, but CT wins on cost
March 5th 2006CT and MR angiography both provided more clinically useful information than duplex ultrasound in screening peripheral vascular disease. But when costs are factored in, CT emerged as the clear leader, according to a four-hospital study conducted in the Netherlands and described Saturday.
MR colonography evolves to meet screening needs
March 3rd 2006MR colonography has yet to capture radiologists’ imagination to the same extent as CT. But the radiation-free exam has a bright future, especially if stool tagging techniques can avoid the need for bowel cleansing, according to speakers from the U.S. and Greece at ECR on Friday.
Nuclear medicine society serves up online CME
March 1st 2006The Society of Nuclear Medicine has launched an online learning program that will enable physicians to earn continuing medical education credits and satisfy stricter new certification requirements at their leisure. Registration is now open for oncology PET and oncology PET/CT.
Nuclear medicine society serves up online CME
March 1st 2006The Society of Nuclear Medicine's recently launched Lifelong Learning and Self-Assessment Program offers online modules to help physicians comply with new maintenance of certification requirements, including 20 nuclear medicine-specific CME credits every year.
Demand overwhelms supply of cardiac CT training slots
March 1st 2006Physicians who plan to perform cardiac CT are in for a surprise. Neither radiologists nor cardiologists are qualified to render diagnoses from multislice CT studies without undergoing more training. The supply of qualified teachers and training slots falls far short of the demands of users to learn this new technology.
Hybrid PET/CT angiography strikes at clinical mainstream
March 1st 2006Before considering revascularization procedures, surgeons want proof of ischemia. While catheter angiography has value in assessing lesions associated with coronary artery disease, it cannot assess the associated ischemia. PET imaging is increasingly being used to provide that information. With the rise of multislice CT angiography as a first-line test for patients with suspected CAD, researchers have set their sights on integrated PET/CT for combined acquisition of coronary anatomy and perfusion.
Government scrutinizes strategic importance of nuclear medicine research
February 14th 2006The Department of Energy and the National Institutes of Health are collaborating on a three-quarter of a million dollar study to determine the importance of nuclear medicine research and to recommend ways to overcome problems that have dogged its pursuit.
MRA contrast selection expands with new compounds
February 11th 2006Contrast agents that can aid MRA examinations have been on the market for more than 15 years. Historically, radiologists could choose from a wide range of agents that, once injected intravenously, would flow through the extracellular space. They would then be excreted from the body relatively rapidly. These extracellular contrast agents are now being joined by a new class of blood pool, or intravascular, contrast agents that bind with molecules in the blood and stay in the circulation for longer.
Expanding contrast options widen clinical utility of MRA
February 11th 2006MR physics dictates that the faster the blood flow, the better the likelihood of quality vessel imaging. Attaining this goal in clinical practice is clearly difficult, given the need for patients to lie still on an MR table for up to 45 minutes. The problem of sluggish blood flow is further compounded in patients with circulatory problems. Yet these are the very individuals who may require MR angiography the most.
CT Colonography gets ready for its close-up
February 11th 2006After twice considering and rejecting endorsement of CT colonography as a cancer screening tool, the American Cancer Society is taking another look. Prompted by advances in reporting standards, technique, and training, the ACS may include the virtual colonoscopy technique as an optional test in its colon cancer screening guidelines by year's end. Such a move, coupled by favorable results from a national clinical trial, could push CTC into the practice mainstream, bolstering adoption, furthering development of computer-aided detection, and most important, fostering reimbursement.
Convert turf battles into productive joint ventures
February 11th 2006Since the introduction of cardiac catheterization in the 1940s, development and implementation of cardiovascular imaging techniques have been a collaborative effort among several specialties, particularly radiology and cardiology. Many pioneers in CV imaging have held joint appointments.
Dual-source CT promises faster scans and lower dose, more data
January 17th 2006The release of Siemens' Somatom Definition may forever change CT. The scanner, unveiled just days before the RSNA meeting and featured at the Siemens booth on the exhibit floor, combines two 64-slice scanners in one, incorporating two x-ray tubes and two detectors. Together, they generate 128 slices every 330 msec. The new product is distinguished less by number of slices or even the novelty of two imaging chains, however, that by what the technology can do: double temporal resolution and cut acquisition time in half.
